ABSTRACT

A multi-cartridge and an aerosol generation device including the same are provided. The aerosol generation device according to some embodiments of the present disclosure may include a first liquid reservoir in which a first liquid composition is stored, a second liquid reservoir in which a second liquid composition different from the first liquid composition is stored, and a vaporizing element configured to vaporize at least one of the first liquid composition and the second liquid composition to generate an aerosol.

TECHNICAL FIELD

The present disclosure relates to a multi-cartridge and an aerosol generation device including the same, and more particularly, to a multi-cartridge which is capable of storing and supplying a plurality of liquid compositions having different compositions and an aerosol generation device including the same.

BACKGROUND ART

In recent years, demand for alternative articles that overcome the disadvantages of traditional cigarettes has increased. For example, demand for devices that electrically heat a cigarette to generate an aerosol (e.g., cigarette-type electronic cigarettes) has increased, and accordingly, active research has been carried out on electric heating-type aerosol generation devices.

Recently, a hybrid-type aerosol generation device that uses a cartridge, which holds a liquid composition including an aerosol-forming agent, and a cigarette together has been proposed. In the proposed aerosol generation device, an aerosol is formed as the liquid composition in the cartridge vaporizes, and the formed aerosol is inhaled through the oral region of a user after passing through the cigarette.

However, in the proposed aerosol generation device, due to removability of the cigarette, the actual amount of vapor produced is significantly less as compared to the aerosol formed in the cartridge. Further, when a flavoring agent is added to the liquid composition, a proportion of the aerosol-forming agent decreases, causing the vapor production to be further reduced. Also, accordingly, the amount of flavoring agent added to the liquid composition is limited, and it is difficult to improve flavor expression.

DISCLOSURE Technical Problem

Some embodiments of the present disclosure are directed to providing a multi-cartridge which is capable of storing and supplying a plurality of liquid compositions having different compositions and an aerosol generation device including the same.

Some embodiments of the present disclosure are also directed to providing a method of adjusting a degree of vaporization of a plurality of liquid compositions stored in a multi-cartridge.

For example, a multi-cartridge may include both a cartridge formed as a single structure in which a plurality of liquid compositions are stored and a cartridge system including a plurality of cartridges in which at least one liquid composition is stored. Various examples of the multi-cartridge will be described below with reference to FIGS. 1 to 3 .

Hereinafter, various embodiments of the present disclosure will be described in detail.

According to various embodiments of the present disclosure, a multi-cartridge having a function of storing and supplying a plurality of liquid compositions having different compositions (or aerosols formed therefrom) may be provided. Here, the liquid compositions having different compositions may not only include a case in which components are different but also include a case in which composition ratios are different. The multi-cartridge may be applied to liquid-type or hybrid-type aerosol generation devices (e.g., 100-1 to 100-3 of FIGS. 7 to 9 ) to enhance flavor expression and vapor production and provide a customized smoking experience to a user. This will be described below.

The above-described multi-cartridge may be implemented in various ways. For example, the multi-cartridge may be implemented in a form in which a plurality of liquid compositions are stored in a cartridge formed as a single structure or may be implemented in a form in which a plurality of cartridges are mounted on a cartridge holder (e.g., 33 of FIG. 3 ). Hereinafter, various examples of implementing the multi-cartridge will be described in detail with reference to the drawings, and for convenience of description, “liquid composition” will be shortened to “liquid.”

FIG. 1 is an exemplary view for describing a multi-cartridge 10 according to some embodiments of the present disclosure.

As illustrated in FIG. 1 , the multi-cartridge 10 according to the present embodiment may have a structure in which a plurality of liquids L1 and L2 are vaporized together in a vaporization space.

Specifically, as illustrated, the multi-cartridge 10 may include a plurality of liquid reservoirs 11 and 12, a wicking element 14, a vaporizing element 15, and an airflow tube 13. However, only the components relating to the embodiment of the present disclosure are illustrated in FIG. 1 . Therefore, those of ordinary skill in the art to which the present disclosure pertains should understand that the multi-cartridge 10 may further include general-purpose components other than the components illustrated in FIG. 1 .

Also, not all of the components illustrated in FIG. 1 may be essential components of the multi-cartridge 10. For example, the multi-cartridge 10 may be implemented in a form in which some of the components illustrated in FIG. 1 are omitted. As a more specific example, the multi-cartridge 10 may be implemented in a form in which the wicking element 14, the vaporizing element 15, and the airflow tube 13 are omitted.

Also, although FIG. 1 illustrates an example in which the multi-cartridge 10 includes the two liquid reservoirs 11 and 12 (or two liquids), the number of liquid reservoirs (or liquids) may be three or more. However, hereinafter, in order to provide convenience of understanding, description will be continued assuming that the number of liquid reservoirs (or liquids) is two unless mentioned otherwise. Hereinafter, each component of the multi-cartridge 10 will be described.

Among the plurality of liquid reservoirs 11 and 12, a first liquid reservoir 11 may store a first liquid L1, and a second liquid reservoir 12 may store a second liquid L2. In other words, the first liquid reservoir 11 and the second liquid reservoir 12 may have liquid storage spaces separated from each other and store different kinds of liquids L1 and L2. For example, the first liquid reservoir 11 and the second liquid reservoir 12 may be formed by a predetermined liquid storage space being divided by a partition. However, the scope of the present disclosure is not limited thereto.

As mentioned above, the first liquid L1 may have a different composition from the second liquid L2. However, a specific composition of each of the liquids L1 and L2 may vary according to embodiments.

In some embodiments, the first liquid L1 may include an aerosol-forming agent, and the second liquid L2 may include a flavoring agent. In this case, vapor production may be enhanced as the first liquid L1 is vaporized, and simultaneously, flavor expression may also be enhanced as the second liquid L2 is vaporized. In other words, since a proportion of the aerosol-forming agent can be increased through the first liquid L1, and separately, a proportion of the flavoring agent can also be increased through the second liquid L2, vapor production and flavor expression can be simultaneously enhanced.

Also, in some embodiments, the first liquid L1 may include a first flavoring agent, and the second liquid L2 may include a second flavoring agent different from the first flavoring agent. In this case, expression of the first flavoring agent may be enhanced as the first liquid L1 is vaporized, and simultaneously, expression of the second flavoring agent may also be enhanced as the second liquid L2 is vaporized. In other words, since a proportion of the first flavoring agent can be increased through the first liquid L1, and separately, a proportion of the second flavoring agent can also be increased through the second liquid L2, the expression of the first flavoring agent and the expression of the second flavoring agent can be simultaneously enhanced.

Also, in some embodiments, the first liquid L1 may include a flavoring agent and an aerosol-forming agent, and the second liquid L2 may also include a flavoring agent and an aerosol-forming agent. Here, the flavoring agent included in the first liquid L1 and the flavoring agent included in the second liquid L2 may be the same or different from each other. In either case, vapor production and flavor expression can be simultaneously enhanced.

Next, the wicking element 14 may absorb the plurality of liquids L1 and L2 stored in the liquid reservoirs 11 and 12, respectively, and transfer the absorbed liquids L1 and L2 to the vaporizing element 15. For example, the wicking element 14 may be implemented using a material that can easily absorb a liquid substance, such as cotton, silica, a bead assembly, and a porous body (e.g., a porous ceramic), but the scope of the present disclosure is not limited thereto. The wicking element 14 may be implemented using any other material (or form) as long as the wicking element 14 can absorb the liquids L1 and L2. The wicking element 14 may be substituted with another type of liquid transfer means known in the art.

Next, the vaporizing element 15 may vaporize the liquids L1 and L2, which are transferred thereto by the wicking element 14, to generate an aerosol. As illustrated, the vaporizing element 15 may be implemented as a heating element (e.g., a heating coil) configured to vaporize the liquids L1 and L2 by heating, but the scope of the present disclosure is not limited thereto. For example, the vaporizing element 15 may be implemented as a vibration element configured to vaporize a liquid through vibrations. However, hereinafter, in order to provide convenience of understanding, description will be continued assuming that the vaporizing element 15 is implemented as the heating element.

FIG. 1 illustrates an example in which the plurality of liquids L1 and L2 are vaporized together by a single vaporizing element 15, but the scope of the present disclosure is not limited thereto, and the vaporizing element 15 may include a first vaporizing element configured to vaporize the first liquid L1 and a second vaporizing element configured to vaporize the second liquid L2. For example, the vaporizing element 15 may include a first heating element configured to heat a portion (e.g., a left side portion) of the wicking element 14 that mostly absorbs and transfers the first liquid L1 and a second heating element configured to heat a portion (e.g., a right side portion) of the wicking element 14 that mostly absorbs and transfers the second liquid L2. In this case, a degree of vaporization (or a degree of supply) of the liquids L1 and L2 can be independently adjusted through power supplied to each vaporizing element.

Next, the airflow tube 13 may be a structure to which a gas such as air or an aerosol A formed (generated) by the vaporizing element 15 is transferred. FIG. 1 illustrates an example in which the airflow tube 13 is disposed at the center of the multi-cartridge 10, but the position of the airflow tube 13 may be changed in any way according to design of an airflow path.

The multi-cartridge 10 according to some embodiments of the present disclosure has been described above with reference to FIG. 1 . Hereinafter, a multi-cartridge 20 according to other embodiments of the present disclosure will be described with reference to FIG. 2 . However, for clarity of the present disclosure, description of content overlapping with the previous embodiment will be omitted.

As illustrated in FIG. 2 , in the multi-cartridge 20 according to an embodiment, a plurality of liquids L1 and L2 are vaporized independently to form aerosols, and then the formed aerosols are mixed.

Specifically, as illustrated, the multi-cartridge 20 may include a plurality of liquid reservoirs 21 and 22, a plurality of wicking elements 24 and 26, a plurality of vaporizing elements 25 and 27, and an airflow tube 23.

The liquid reservoirs 21 and 22 may correspond to the liquid reservoirs 11 and 12 of the previous embodiment. Therefore, description thereof will be omitted.

Next, among the plurality of wicking elements, a first wicking element 24 may absorb a first liquid L1 from a first liquid reservoir 21 and transfer the absorbed first liquid L1 to a first vaporizing element 25. Also, a second wicking element 26 may absorb a second liquid L2 from a second liquid reservoir 22 and transfer the absorbed second liquid L2 to a second vaporizing element 27.

Next, among the plurality of vaporizing elements 25 and 27, the first vaporizing element 25 may vaporize the first liquid L1 to generate a first aerosol, and the second vaporizing element 27 may vaporize the second liquid L2 to generate a second aerosol. The generated first aerosol and second aerosol may meet in a predetermined mixing space and be mixed therein, and the mixture may flow through the airflow tube 23. Alternatively, the first aerosol and the second aerosol may be mixed in the airflow tube 23.

Next, the airflow tube 23 may correspond to the airflow tube 13 of the previous embodiment. Therefore, description thereof will be omitted.

The multi-cartridge 20 according to some embodiments of the present disclosure has been described above with reference to FIG. 2 . Hereinafter, a multi-cartridge 30 according to other embodiments of the present disclosure will be described with reference to FIG. 3 .

As illustrated in FIG. 3 , the multi-cartridge 30 according to the present embodiment may be formed to have a structure in which a plurality of cartridges 31 and 32 are mounted. To this end, the multi-cartridge 30 may be configured to include the plurality of cartridges 31 and 32 and a cartridge holder 33.

Each of the cartridges 31 and 32 may correspond to a single cartridge or the above-described multi-cartridge (e.g., 10 or 20). Each of the cartridges 31 and 32 may only serve to store the liquids L1 and L2 or also serve to vaporize the liquids L1 and L2. Each of the cartridges 31 and 32 may be mounted on or detached from the cartridge holder 33. In order to avoid repeated description, further description of the cartridges 31 and 32 will be omitted.

Next, the cartridge holder 33 may have a structure on which the plurality of cartridges 31 and 32 are mountable. The cartridge holder 33 may only serve to allow the plurality of cartridges 31 and 32 to be mounted thereon or also serve to adjust a degree of supply or a degree of vaporization of the liquids L1 and L2 stored in the cartridges 31 and 32, respectively. The method of adjusting the degree of vaporization of the liquids L1 and L2 will be described in detail below with reference to FIGS. 4 and 5 .

The multi-cartridge 30 according to some embodiments of the present disclosure has been described above with reference to FIG. 3 . Hereinafter, various ways in which a degree of vaporization (or degree of supply) of a stored liquid (e.g., L1) is adjusted in the above-described multi-cartridges 10 to 30 will be described with reference to FIG. 4 and so on.

FIGS. 4 and 5 are exemplary views for describing ways in which a degree of vaporization is adjusted in a multi-cartridge 40 according to some embodiments of the present disclosure. In particular, in FIGS. 4 and 5 , for convenience of understanding, illustrations of components such as a wicking element (e.g., 14), a vaporizing element (e.g., 15), and an airflow tube (e.g., 13) have been omitted. Also, the multi-cartridge 40 illustrated in FIGS. 4 and 5 may correspond to the multi-cartridges 10 to 30 described above with reference to FIGS. 1 to 3 , and directions and thicknesses of arrows in FIGS. 4 and 5 indicate liquid transfer directions and amounts of transferred liquid. Also, FIGS. 4 and 5 illustrate a case in which the transfer amount of second liquid L2 is adjusted to be larger than the transfer amount of first liquid L1.

As illustrated in FIGS. 4 and 5 , the first liquid L1 stored in a first liquid reservoir 41 may be transferred through a first transfer path 43, and the second liquid L2 stored in a second liquid reservoir 42 may be transferred through a second transfer path 44. For example, the first liquid L1 may be transferred to a wicking element (e.g., 14) or a vaporizing element (e.g., 15) through the first transfer path 43.

In such a case, the multi-cartridge 40 may adjust a degree of vaporization of the liquids L1 and L2 by using adjusting members 45 to 48 configured to adjust a degree of opening of the liquid transfer paths 43 and 44. Specifically, the multi-cartridge 40 may include first adjusting members 45 and 47 configured to adjust the degree of opening of the first transfer path 43 and second adjusting members 46 and 48 configured to adjust the degree of opening of the second transfer path 44. Also, as the degree of opening of each of the transfer paths 43 and 44 is adjusted by the adjusting members 45 to 48, a degree of supply (e.g., a supply speed, a supply amount) of the liquids L1 and L2 may be adjusted. Also, as a result, the degree of vaporization of each of the liquids L1 and L2 may be adjusted. For example, as the first adjusting member 45 closes the first transfer path 43, vaporization of the first liquid L1 may be stopped, and as the first adjusting member 45 completely opens the first transfer path 43, the vaporization of the first liquid L1 may be accelerated.

Meanwhile, the adjusting members 45 to 48 may be implemented in various ways.

As an example, as illustrated in FIG. 4 , the adjusting members 45 and 46 may be implemented as structures that are disposed perpendicular to the liquid transfer paths 43 and 44 to open or close the liquid transfer paths 43 and 44.

As another example, as illustrated in FIG. 5 , the adjusting members 47 and 48 may be implemented as rotary plates in which a plurality of holes 481 and 482 of different sizes are formed. The rotary plate 48 may adjust a degree of supply of the liquids L1 and L2 through the plurality of holes 481 and 482. For example, as a first hole 481 having a relatively smaller size is located on a second liquid transfer path 44 due to rotation of the rotary plate 48, a supply amount of the second liquid L2 may be relatively decreased. On the other hand, as a second hole 482 having a relatively larger size is located on the second liquid transfer path 44 due to rotation of the rotary plate 48, the supply amount of the second liquid L2 may be relatively increased. Of course, as a portion where a hole (e.g., 481 or 482) is not formed is located on the second liquid transfer path 44 due to rotation of the rotary plate 48, the supply of the second liquid L2 may be stopped.

However, the scope of the present disclosure is not limited by the above-described examples, and the adjusting members 45 to 48 may be implemented on the basis of various forms of valve structures known in the art.

Meanwhile, according to other embodiments of the present disclosure, the degree of vaporization of the liquids L1 and L2 may be adjusted through power supplied to the vaporizing elements (e.g., 25, 27). For example, a degree of vaporization of the first liquid L1 may be adjusted by adjusting power supplied to the first vaporizing element (e.g., 25) configured to vaporize the first liquid L1. This is because a vaporization amount (or vaporization speed) of the first liquid L1 will increase with an increase in the power supplied to the first vaporizing element (e.g., 25). The power supplied to the vaporizing elements (e.g., 25, 27) may be controlled by a controller (e.g., 120 of FIG. 7 ).

The ways in which the degree of vaporization of the liquids L1 and L2 is adjusted in the multi-cartridge 40 have been described above with reference to FIGS. 4 and 5 . According to the above description, by adjusting the degree of opening of the liquid transfer paths 43 and 44 using the adjusting members 45 to 48 or adjusting the power supplied to the vaporizing elements (e.g., 25, 27), the degree of vaporization of the liquids L1 and L2 may be accurately and easily adjusted.

Hereinafter, a method of providing a customized smoking experience using the above-described multi-cartridge 40 will be described with reference to FIG. 6 . In particular, FIG. 6 illustrates an example in which a multi-cartridge consists of three cartridges (or liquid reservoirs) 51 to 53 which store different liquids L1 to L3, respectively. Hereinafter, description will be given with reference to FIG. 6 .

When a degree of vaporization of each of the liquids L1 to L3 is adjusted as described above, a customized smoking experience can be provided to a user. Specifically, when the degree of vaporization of each of the liquids L1 to L3 is adjustable by a user input, types and amounts of components included in aerosols (e.g., A1, A2) may be changed according to a user input, and thus a customized smoking experience can be provided to the user. In other words, a user may adjust the degree of vaporization of each of the liquids L1 to L3 according to his or her preferences, and thus a customized smoking experience can be provided to the user. For example, the controller (e.g., 120 of FIG. 7 ) may adjust the degree of vaporization of each of the liquids L1 to L3 on the basis of a received user input to generate customized aerosols (e.g., A1, A2). However, the scope of the present disclosure is not limited thereto.

As a specific example, as illustrated, a user may adjust a first liquid L1 and a second liquid L2 to be vaporized in equal proportions to generate a customized aerosol A1 in which components of the first liquid L1 and the second liquid L2 are uniformly combined. For example, a user may generate an aerosol in which components of a first flavoring agent and components of a second flavoring agent are uniformly combined.

Alternatively, a user may adjust a first liquid L1, a second liquid L2, and a third liquid L3 to be vaporized in different proportions to generate a customized aerosol A2 in which components of the first to third liquids L1 to L3 are combined in different proportions. For example, a user may generate an aerosol in which components of a first flavoring agent, a second flavoring agent, and a third flavoring agent are combined in different proportions.

In some embodiments, a multi-cartridge may be configured as illustrated in FIG. 3 . In this case, a user may mount a cartridge containing a preferred liquid on a cartridge holder (e.g., 33) and receive a customized smoking experience by changing a degree of vaporization of the liquid. Also, the user may receive various smoking experiences by changing the cartridge mounted on the cartridge holder (e.g., 33).

Also, according to some embodiments of the present disclosure, the controller (e.g., 120 of FIG. 7 ) of an aerosol generation device (e.g., 100-1 of FIG. 7 ) to which the multi-cartridge is applied may provide various convenience functions for a customized smoking experience.

For example, the controller (e.g., 120 of FIG. 7 ) may provide a function of storing and loading combination information of a liquid. Here, the combination information may include information on the type of liquid and a degree of vaporization of the liquid. In this example, when an aerosol having preferred characteristics is formed, a user may store combination information including the type of liquid and a degree of vaporization of the liquid and may later load the stored information to be provided with the preferred aerosol again.

As another example, the controller (e.g., 120 of FIG. 7 ) may provide a function of storing a history of combination information of a liquid. Also, the controller may separately store or recommend to a user a liquid combination repeatedly used by the user or liquid combinations used in succession by the user.

As still another example, the controller (e.g., 120 of FIG. 7 ) may provide an automatic liquid combining function. As a more specific example, the controller may randomly combine a plurality of liquids (e.g., randomly determine and combine types of liquids and degrees of vaporization thereof) and provide the liquid combination to a user (e.g., randomly combine types of liquids and degrees of vaporization thereof upon each puff and provide the liquid combination to the user). Alternatively, when a user has designated a base liquid, the controller may randomly combine another liquid with the base liquid and provide the liquid combination to the user. Alternatively, the controller may determine a base liquid on the basis of a liquid combination history (e.g., determine a frequently-used liquid, a liquid with a short usage interval, a recently-used liquid, or the like as the base liquid), randomly combine another liquid with the determined base liquid, and provide the liquid combination to the user. Alternatively, the controller may, on the basis of a liquid combination history, combine liquids with a recipe not experienced by a user (e.g., combine liquids with proportions not present in the existing history) and provide the liquid combination to the user. Alternatively, the controller may change a combination of liquids on the basis of degrees of consumption of the liquids (e.g., reduce a degree of vaporization of a liquid that is consumed more or consumed at a high speed or increase a degree of vaporization of a liquid that is consumed less or consumed at a low speed) and provide the liquid combination to the user.

The method of providing a customized smoking experience by using the multi-cartridge (e.g., 40) according to some embodiments of the present disclosure has been described above with reference to FIG. 6 . Hereinafter, various types of aerosol generation devices 100-1 to 100-3 to which the above-described multi-cartridges (e.g., 10 to 40) may be applied (or which include the above-described multi-cartridges) will be described with reference to FIGS. 7 to 9 .

FIG. 7 is an exemplary view schematically illustrating the aerosol generation device 100-1 according to some embodiments of the present disclosure.

As illustrated in FIG. 7 , the aerosol generation device 100-1 may include a housing, a mouthpiece 110, a vaporizer 1, a battery 130, and a controller 120. However, only the components relating to the embodiment of the present disclosure are illustrated in FIG. 7 . Therefore, those of ordinary skill in the art to which the present disclosure pertains should understand that the aerosol generation device 100-1 may further include general-purpose components other than the components illustrated in FIG. 7 . For example, the aerosol generation device 100-1 may further include an input module (e.g., a button, a touchable display, etc.) for receiving a command or the like from a user and an output module (e.g., a light emitting diode (LED), a display, or a vibration motor, etc.) for outputting a state, smoking information, or the like of the aerosol generation device 100-1. Hereinafter, each component of the aerosol generation device 100-1 will be described.

The housing may form the overall exterior of the aerosol generation device 100-1. The housing may be implemented using a material that can protect components therein.

Next, the mouthpiece 110 may be disposed at one end of the aerosol generation device 100-1 and come into contact with the oral region of a user. By making a puff while holding the mouthpiece 110 in his or her mouth, the user may inhale an aerosol generated from the vaporizer 1.

Next, the vaporizer 1 may vaporize a liquid composition to generate an aerosol. The vaporizer 1 may be a component that corresponds to the above-described multi-cartridges (e.g., 10 to 40) or may be a component that includes the above-described multi-cartridges (e.g., 10 to 40). In order to avoid repeated description, further description of the vaporizer 1 will be omitted.

Next, the battery 130 may supply power used to operate the aerosol generation device 100-1. For example, the battery 130 may supply power to allow the vaporizer 1 to generate an aerosol and may supply power required for the operation of the controller 120.

Also, the battery 130 may supply power required to operate electrical components such as a display (not illustrated), a sensor (not illustrated), and a motor (not illustrated) which are installed in the aerosol generation device 100-1.

Next, the controller 120 may control the overall operation of the aerosol generation device 100-1. For example, the controller 120 may control the operation of the vaporizer 1 and the battery 130 and may also control the operation of other components included in the aerosol generation device 100-1. The controller 120 may control the power supplied by the battery 130, a vaporization speed of the vaporizer 1, and the like. Also, the controller 120 may check a state of each of the components of the aerosol generation device 100-1 and determine whether the aerosol generation device 100-1 is in an operable state.

The controller 120 may be implemented with at least one controller (processor). The controller may also be implemented with an array of a plurality of logic gates or implemented with a combination of a general-purpose microcontroller and a memory which stores a program that may be executed by the microcontroller. Also, those of ordinary skill in the art to which the present disclosure pertains should understand that the controller 120 may also be implemented with other forms of hardware.

Hereinafter, other types of aerosol generation devices 100-2 and 100-3 will be described with reference to FIGS. 8 and 9 . However, for clarity of the present disclosure, description of content overlapping with the previous embodiment will be omitted.

FIGS. 8 and 9 are views for describing the aerosol generation devices 100-2 and 100-3 according to some embodiments of the present disclosure. In particular, FIG. 8 and so on illustrate examples in which an aerosol-generating article 150 is accommodated (inserted) in the devices 100-2 and 100-3.

As illustrated in FIGS. 8 and 9 , the aerosol generation devices 100-2 and 100-3 according to the present embodiment may further include a heater part 140 configured to heat the aerosol-generating article 150. Also, the aerosol generation devices 100-2 and 100-3 may have an airflow path formed to allow an aerosol generated in the vaporizer 1 to pass through the aerosol-generating article 150 and be delivered to the user.

FIG. 8 illustrates a case in which the heater part 140 (or the aerosol-generating article 150) and the vaporizer 1 are disposed in parallel, and FIG. 9 illustrates a case in which the heater part 140 (or the aerosol-generating article 150) and the vaporizer 1 are disposed in series. However, an internal structure of the aerosol generation devices 100-2 and 100-3 is not limited to the examples of FIGS. 8 and 9 , and the arrangement of the components may be changed in any way.

The heater part 140 may heat the aerosol-generating article 150 accommodated in an accommodation space. The accommodation space may be formed by housings of the aerosol generation devices 100-2 and 100-3. Specifically, when the aerosol-generating article 150 is accommodated in the accommodation spaces of the aerosol generation devices 100-2 and 100-3, the heater part 140 may heat the aerosol-generating article 150 using power supplied from the battery 130.

An operation method and/or an implementation form of the heater part 140 may vary.

For example, the heater part 140 may operate using a resistive heating method. For example, the heater part 140 may include an electrically insulating substrate (e.g., a substrate formed of polyimide) and an electrically conductive track and may include an electrically-resistive heating element configured to generate heat as current flows in the electrically conductive track.

As another example, the heater part 140 may operate using an induction heating method. For example, the heater part 140 may include an induction coil and a heating element (that is, a susceptor) inductively heated by the induction coil. The susceptor may be disposed outside the aerosol-generating article 150 or inside the aerosol-generating article 150.

However, the scope of the present disclosure is not limited to the above examples, and the heater part 140 may operate using any other method as long as the heater part 140 can heat the aerosol-generating article 150 to a desired temperature. Here, the desired temperature may be preset in the aerosol generation devices 100-2 and 100-3 (e.g., a temperature profile may be prestored therein) or may be set by the user.

The aerosol-generating article 150 may have a structure similar to that of a general combustion-type cigarette. For example, the aerosol-generating article 150 may be divided into an aerosol-forming substrate part which includes an aerosol-forming substrate (e.g., an aerosol-forming agent, a nicotine-generating substrate, etc.) and a filter part which includes a filter material. At least a portion of the aerosol-forming substrate part may be inserted into the aerosol generation devices 100-2 and 100-3, and the filter part may be exposed to the outside, but the present disclosure is not limited thereto. The user may smoke while holding the filter part in his or her mouth.

All the components constituting the embodiments of the present disclosure have been described above as being combined into one body or being operated in combination, but the technical spirit of the present disclosure is not necessarily limited to the embodiments. That is, any one or more of the components may be selectively operated in combination within the intended scope of the present disclosure.
